###### Question:

A spacecraft orbits the Earth unpowered in a circular path at a height of h = 365km above the Earth's surface. At position A thrusters are applied briefly that DOUBLE the satellite's speed. RE = 6,380,000m; ME = 5.98E24kg; G = 6.673E-11N.m 2/kg 2; Earth (a) What is the period the spacecraft(in seconds) before the thrusters are applied? 5428 sec (b) What is the angular velocity of the craft at B (WB), where the radius has increased by 19percent from the circular orbit radius? Number Units
